Step-by-step explanation:
Among the given options, Mass Customization is not a way U.S. auto mass producers operate.
Mass customization refers to the production of goods in large quantities with the ability to customize and tailor products to individual customer preferences. It allows consumers to choose various options and features to create a personalized product.
U.S. auto mass producers, on the other hand, typically operate through assembly line production, where products are sequentially assembled with each worker adding specific components at different stations. Just-in-time inventory management is also commonly used, where parts are delivered as needed to minimize storage and inventory costs. Additionally, batch production is another mode of operation, where products are manufactured in distinct batches based on customer demand or specific requirements.
